A client that waits in ifup's foreground on a server's answer holds the whole machine, because init starts the rest of the boot - sshd, forgectrl, the console login - only after S01networking returns. A field machine sat there forever on a router that refused DHCPv6 (the record is in the meta-openglow commit that drops the DHCPv6 client). Nothing in the catalog looked at the network boot path; this test does. It asserts: wlan0 is in ifupdown's state file and no ifup is running; the console getty is up; udhcpc runs with -b (it leaves ifup after three unanswered discovers) and has been reparented to init; no DHCPv6 client is named in /etc/network/interfaces, running, or on the image, and its hook script is gone; IPv6 on wlan0 is the kernel's own - enabled, router advertisements accepted, a link-local address up. A global address is evidence only: a network whose router advertisement offers no SLAAC prefix gives none. What a hostile server does to a client is a bench drill, not a test. covers is empty by design, as with setup.machine-name: the interfaces file is layer content, in the platform identity of every fingerprint, so a change there already makes every test necessary again. Proven: the host tests for the parsers and the registration (tests/test_image.py), and the whole host suite, 398 tests, under Linux. The test's logic, run read-only on the bench reference against an image that carries the client, fails exactly the four DHCPv6 checks and passes every other one. The test fails on any image built from a meta-openglow that still carries the client, so the kas lock moves to the layer head that drops it.
OpenGlow / ForgeFIRM firmware for Glowforge
BETA
ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. Expect problems, and expect frequent updates. Upgrade whenever a newer release is available, and report what you find on the community forum.
Open firmware for Glowforge brand CNC lasers. ForgeFIRM replaces the cloud-dependent factory software on the stock control board, with no hardware modification, and gives the machine a local controller, a local web control panel, and a standard Grbl interface. The factory cloud experience stays available as an option.
This repository is the base of the build and of the release: the
meta-forgefirm Yocto layer, the kas configuration, the image recipes, the
install and release scripts, the acceptance tool (forgetest/), the bench
tools (scripts/bench/), the bench actuator firmware (fixture/), and the
release artifacts (releases/).

Build
kas build kas/forgefirm-glowforge.yml
Build covers the host setup, the two images, the source variant and the debug kernel. Release flow covers the pins, the push order and the signing pipeline.
Test
cd forgetest && python3 -m unittest discover -s tests -v
The acceptance catalog that gates a release, and the bench tools, are on Acceptance and The bench.
Contributing
AGENTS.md carries the rules for this repository and for the project: safety ordering, proof before done, the push order, and the writing rules. They apply to human contributors too, and Contribute is the same set on the site.
What this costs
Nothing. ForgeFIRM is free in both senses, under MIT and GPL licenses. There is no paid tier, no license key, no subscription and no Pro edition. If someone offers to sell it to you, the licenses allow it, but what you take home is their build rather than this one: get it from the source.
Safety
These machines contain a CO2 laser: it burns, blinds, and starts fires. Never defeat the lid switches or the interlock. Never leave a running job unattended. Keep a fire extinguisher within reach. Read Safety before you cut your first job, and Regulatory and legal before you install.
This is experimental software. Use of it could seriously maim or kill you or others, and it may void your warranty. Use it at your own risk.
